COMPRESSOR OR TERMINAL FOE GOIL-SERINGS.

Specification of Letters Patent.

Patented July 2, 1918.

Application filed April 6, 1917. Serial No. 160,279.

To all whom it may concern:

Be it known that I, ALBERT A. HANSEN, a citizen of the United States, residin at Kenmare, in the county of Ward and tate of North Dakota, have invented certain new and useful Improvements in Compressors or Terminals for Coil-Springs, of which the following is a specification.

This invention relates to a compressor or terminal for coil springs and has primarily for an object to produce a removable spring terminal which can be readily connected to and engaged with the coils of the springs, and by a very simple manipulation will snugly engage the convolutions of the spring after the latter has been unduly extended or elongated.

Other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claim forming a part of this specification.

In the drawings:

Figure 1 is a perspective view of my improved compressors illustrating the application thereof, and

Fig. 2 is a similar enlarged view showing the same attached to a portion of a coil spring.

In the drawings, in order to illustrate the application of my invention a coil spring 1 is shown.

My improved compressor and removable spring terminal in this instance comprises a wire strand 2, the ends of which are bent toward each other as indicated at 3. In bending the endstogether, care is taken so that one of the ends, as indicated at 4, will be appreciably longer than the other for a purpose which will hereinafter be more fully set forth. The ends are brought in close proximity to each other so as to provide an open loop, after which the terminals are reversely turned to provide substantially ovoid hooks 5 and 6. The hook 6 is, of course, in a plane slightly below the plane of the hook 5 so that said hook 6 will first engage the terminal convolution of the coil spring 1. After the hook 6 has been engaged with one of the terminal convolutions of the spring the strand 2 is turned, causing the hook 5 to slide around beneath the next convolution until the hook has been engaged with the terminal convolution. A compressor or terminal is then engaged with the opposite end of the coil spring in the manner indicated above. The compressors or spring terminals are then grasped between the thumb and first finger of the hands of the operator and turned in opposite directions, thereby snugly engaging the convolutions of the spring. It is appreciated that if sufiicient pressure is exerted upon the compressors or terminals, the spring will be restored to its normal condition, even though the convolutions thereof have been strained by undue distention.

It will be understood that the above description and accompanying drawings comprehend only the general and preferred embodiment of my invention and that various minor changes in details of construction, proportion and arrangement of parts may be made within the scope of the appended claim without sacrificing any of the advantages of my invention.

I claim A removable terminal for helical springs, which comprises a single strand of wire bent to form an open loop, the ends of which lie relatively close together, and the free ends of the strand having hooks formed thereon, and one of said free ends being extended beyond the other, said ends being adapted to engage with the convolutions of the spring helix and being interposed therein by a rotative movement of the loop.

In testimony whereof I afiix my signature in presence of two witnesses.
